:SPECIFICATION forming part of Letters Patent No. 425,673, dated April15, 1890.

Application filed December 13, 1889. Serial No.3 33,641. (No model.)

To all whom t may concern: thereof acting as a float and lifting theopen Be it known that I, JOHN HEBERLING, a mouth off the bottom of theink-reservoir to citizen of the United States, residing at Rochpermitthe ink to flow freely to the interior ester, in the county of Monroeand State of of the collapsible or air-compressing chamber 55 5 NewYork, have invented new and useful to supply the consumption takingplace in Improvements in Fountain -Inkstands, of the fountain-cup. whichthe following is a specification. It is also my purpose to provide anink- My invention relates to that type of inkstand of this type in whichthe ink shall be stands in which a fountain-cup is lled and caused toflow to and from the fountain-cup 6o ro emptied by the flow of ink toand from a resat each dip of the pin, means being provided, ervoir orchamber communicating with said however, wherebyT apermanently-remaining cup. supply may be given in the fountain-cup forIt is the purpose of my invention to provide any required period andremoved at intervals, an inkstand of this type in which the flow as maybe necessary. 65 I 5 and return to and from the fountain-cup shall Theinvention consists in the several novel be effected by a compressibleand expansible features of construction and new combinaelastic cupmounted upon the lower portion tions of parts hereinafter fully setforth, and of the tubular stem, which also carries the then definitelypointed out in the claims folfountain-cup, the said elastic cup seatingupon lowing vthis specification. 7o zo its open neck or mouth upon thebottom of To enable others skilled in the art to pracanink-reservoirwith which, however, it has tice my said invention, I willdescribe the no positive connection, whereby the eXpansame in detail,reference being had to the acsion of the air by change of temperaturecompanying drawings, in which-- within the inkstand proper shall nothave the Figure l is a central vertical section of an 75 2 5 effect ofiiooding the fountain-cup, while the inkstand, showing my invention.Fig. 2 is a elastic cup by which the fountain is supplied similarsection showing the same parts in a shall be shielded from suchaccidental eXpandifferent position. Fi g. 3 is an elevation showsion,the air-compression by which said cup ing the device locking thefountain-cup in is illed being wholly confined to said elastic thatposition in which it affords a permanent 8o 3o cup and being whollyremoved from the main supply of ink. Fig. I is a detail perspective inkchamber or reservoir. of the collapsible cup, the tubular stem, and

It is my purpose also to provide afountainthe fountain-cup mountedthereon. inkstand wherein the supply to the fountain- In the saiddrawings, the reference-numeral cup shall be effected by acontractingand exl denotes the body of the inkstand, which 85 35 panding cup, theelastic portion of which is may be of any preferred form, size, andornapenetrated by the tubular stem which commentation and constructedfrom any matemunicates with and carries the fountain-cup, rial suitablefor the purpose which will not the construction being such that theelastic readily corrode bythe acids of the ink. This cup or vessel shalllie in and be supplied from body incloses a reservoir 2 of any shape and9o 40 the ink-reservoir of the stand, from which the size preferred, acentral depression or chamink fiows to the interior of the elastic cupat ber 3 of small diameter and shallow depth or after each rise of thefountain-cup. v In being formed in the bottom, although this is otherwords, I combine with any ordinary ink not absolutely essential.reservoir or chamber an elastic collapsible The reservoir 2 is closed atthe top by acap 95 45 cup or auxiliary reservoir, consisting of an orcover 4, which is formed of any suitable mainverted vessel partly filledwith air and havterial-such as hard rubber-and connected ing its closedcollapsing upper portion peneto the body by any known or preferred formtrated by the tubular stem of the fountainof joint which will preventthe escape 0f the cup, which drops within said collapsible chaminkshould the inkstand be capsized. In the roc 5o ber to a point where itsopen end is submerged, cap or cover et 1s formed a centralsocket-bearsaid chamber or cup at each full expansion ing 5 of ordinaryconstruction, within which therewith.

is arranged a tubular stein 6, having a neck 7, which closely fits theupper part of the socket. This stem is prolonged to extend nearly to theplane of the bottom of the reservoir 2, and upon the lower part thereofis mounted a vesselor cup 8, having an expanded collapsible closedportion 9 and a more, rigid open neck or mouth 10, which, althoughformed wholly or in part of yielding or elastic material, is intended toyield only so far as to form a practically tight joint at the pointwhere it seats upon the bottom of the reservoir 2 and around thecentraldepression 3. The elastic and collapsible portion 9 islpenetra'ted bythe tubular stem 6, which centrally overhangs the recess or depression3, the point of penetration being sealed by nuts or washers 12, turnedonua threaded portion of the stem and between `which the material iscompressed. A fountain-cup 13 of any suitable construction is mounted onthe stem and communicates On the stem is also mounted a washer 14, whichlies normally against the lower surface of the socket-bearing and closesthe reservoir againstthe accidental escapeof ink. p

The reservoir 2 being partly filled with ink,

the cover is placed thereon, thereby submerging the collapsible cup, ornearly so, and producing therein a compression of air, whereby the inkis allowed to rise in the `neck 10 far enough to submergc the open endof the tubular stem 6. The vessel or cup under these conditions becomesa float and tends to rise by its own buoyancy, and if the fitting at thesocket-bearing is ordinarily accurate it will Lrise until the neck 10 isslightly raised from the bottom of the reservoir-'2, thereby permittingink to dow from the latter into the central depression 3 and into theneck 10 of the cup. The further rise of the latter is limited by thewasher 14, seating upon the socket-bearing 5. When the fountain-cup ispressed downward, the neck 10 seats upon the bottom of the reservoir '2around the recess or depression 3 and forms a practically tight joint,which prevents the ink fromy entering or escaping. Y A further pressurenow causes a partial collapse of the elastic portion 9, compressing theairf therein and driving the ink up through the tubular stem 6 into thefountain-cup, filling the same, the stem atthe same time sinking withinthe central depression 3 until an elastic or yielding collar or packing15, mounted on and surrounding its open end, seats upon the bottom `ofthe depression and closes the stem, thereby retaining the ink whichfills the fountain-cup as long as this position and engagement of partsare preserved.

The ink may be caused to flow to the fountain-cup and recede therefromeach time the pen is dipped, or the cup may be filled and its supplyretained until exhausted, To eect this result, I tap into the cover orcap 4 a setvscrew 16, having a cam-collar 17, which may :be milled, andwhich by rotating: said screw in the manner described, such device beingindependent of and separate from the tubular stem and socket-bearingtherefor.

\ The washer14 is applied `to the stem in` any manner-as, for example,by being slipped over a circumferential series of corrugations 19. Itwill be seen that I may dispense with the central depression or recessj3and use a reservoir having a perfectly-fiat bottom; but in this case itwill be preferable to increase the height of the neck 10 ofthe thevessel or cup 9.

It will be seen that the elastic expansion l of the collapsible invertedcup after each flow of ink to the fountain-,cup will not only `restorethe latter to normal position, but will tend to preserve the necessaryquantity of y.

ink within the neck of the elastic cup and in the depression surroundedby it.
